I never heard of what DBFSD means or anything but DBFS...there is no BEST NUMBER, 0dbvu simply means -18dbfs and that is theBEST NUMBER...but still depends what standard you are using.It can be also in LUFS which is usually recommended at -23lufswhich would equal to -23dbfs. I calibrate with Sine Wave at-20dbfs and start from there, i mostly use EBU R128 Standard.

I hadn't heard of it before either. I supposed it may have something to do with D-dynamic range even though there are no consistencies with analog db references and dbfs. Typo? Nobody's perfect, even a Genius. It was in his 1st response to me, right above yours. Thanks.

- dB is decibel (bel is the unit, should be B and not b).- FS is full scale.- D is digital, no D means could be analog or digital domain.

EBU recommend to still calibrate with -18 dBFS for both EBU-r68 and EBU-r128. If you calibrate with -20 dBFS you are using SMTPE RP-155, difference between both is 6 dB and not 2 dB. So SMTPE RP-155 will work better with bigger dynamic range audio programs, you can even go below for example calibrate at -24 dBFS but will depend the noise floor of your system.

You should research all your system, from recording inputs to loudspeakers and the studio acoustical sound pressure in dBSPL, for example normally audio interfaces are calibrated to -18 dBFS and several ones to -24 dBFS while converters normally are calibrated to work at -15 dBFS that is the old CD standard, add N**e or Midas console distort around 24 to 26 dBu.

(Time for buy a voltmeter tester)

My console input peak light (20) comes on at +21dbu (11.3 dbv). I also measured my DAW output at 1.2dbu - outputting -10 dbfs) When I look at the Aruora software interface it was reading quite low at +24 dbfs, naturally. So I proceded to bump it. At this point I contacted the forum. Keep in mind I'm "thinking" OTB, trying to arrive at my landing strip, trying diligently to get there in a reasonable, more scientific way along with my ears. Yes, my equivalent overall dbfs was -24-thanks to Giancarlo letting me know. Since I am using a console and outboard it was too low for good SNR-around 64 dbu, maybe a little less. My DAW faders were all at scale "0" so I had plenty of room to bump each by a close 3db. There was a nice sweet spot around -24 but raising everything by that amount gives me now an overall SNR around 73/4 dbu. I can live with that easily-still nothing like my old Ampex AG440B 8 track without dolby. I did the old bump the high end for record and lower for playback "thing"-not by much. I loved the sound and miss it, but you Acustica guys have gotten me so much closer. It warms my heart to thank you.
